Transparent colourants and colourant compositions, and their use

ABSTRACT

A colorant composition comprising in a weight ratio of from 99:1 to 10:90, a pigment of average particle size from 10 to 200 nm and a compound of the formula

The invention relates to the field of pigmented colour filters.Normally, trichromatism is achieved by using one blue, one red and onegreen filter, or alternatively one yellow, one magenta and one cyanfilter. These filters must be highly transparent, homogeneous and ableto be prepared in a very uniform layer thickness with precise pattern.

The correct position and the absolute value of the transmission windoware very important parameters for colour filters. There is a desire forhigh transmission in the wavelength range surrounding the lightemission, coupled with as high as possible an absorption fordifferent-coloured light. In addition, there is a strongly increasingdemand for a higher display contrast (ratio of luminances in the ON/OFFstates).

EP-A-1 291 379 discloses optical films for plasma displays, comprisingviolet to blue anthraquinone type colourants and a near infraredabsorber. The purpose of using violet to blue colourants and infraredabsorbers in plasma displays is to correct the colour tone and avoidinterference with infrared remote controls by absorbing the undesirablelight emissions of the usual neon/xenon light sources at 590 nm (Ne) andat 850 nm and above (Xe). These optical films are homogeneouslycoloured.

WO-03/035770 discloses a process for making green pigment compositionsfor colour filters by kneading both components with salt in the presenceof a liquid.

JP-A-H05/331378 discloses pigment compositions for colour filterscomprising yellow anthraquinone pigments of the formula

JP-A-2000/281928 discloses pigment compositions for pseudo yellow colourfilters comprising anthraquinone pigments for example of the formula

C. I. Solvent Yellow 167 is a known solvent dye of the formula

Substituted derivatives thereof have been used for example asintermediates (US-A-2004/0232382), as pleochroic colourants for liquidcrystals (JP-A-2003/238963, DE-A-33 14 467 or GB-A-2082196) or asdisperse dyes for textile materials (WO-2005/024123), optionally usinginkjet printing (WO-2005/040492).

CAS Registry [73507-58-1] is a compound about which nothing else but theformula is known:

Further known compounds are disclosed in U.S. Pat. No. 4,359,570, U.S.Pat. No. 4,420,581, EP-A-0040 139, JP-A-S62/064865 and DE-OS-2200 115.

It has now surprisingly been found that the transmission of pigmentedcolour filters is improved by adding certain 1- or2-phenylthio-substituted anthraquinones of greenish-yellow colour hue,lacking electron-rich N^((III)), O^((II)) and further S^((II))substituents on the anthraquinone ring.

Especially preferred are pigments, the visible light absorption maximaof which are in the range from 400 to 500 nm and/or from 600 to 700 nm.The visible light range is from 400 to 700 nm. Most preferred pigmentsare green pigments, in particular halogenated phthalocyanine pigments,especially Colour Index Pigment Green 7, 17, 36 and/or 37. However, itis also suitable to use pigments, the visible light absorption maxima ofwhich are in the range from 500 to 570 nm, in which case the hue angle hof the red pigment is shifted to higher values (CIE-L*C*h colour space).

The instant composition preferably further comprises a photoresist asdescribed below, for example a photoinitiator and a polymerisablemonomer.

Thus, the invention further pertains to a composition comprising from0.1 to 70% by weight of a colourant comprising a pigment of averageparticle size from 10 to 200 nm and a compound of formula (I) or (II) ina weight ratio of from 99:1 to 10:90, preferably a weight ratio of from95:5 to 30:70, and a liquid medium comprising a binder or apolymerisable compound.

The 1- or 2-phenylthio-anthraquinone dye can be used as a pure compound,or optionally as a mixture of several 1- and/or2-phenylthio-anthraquinone dyes of different structures, for examplemixtures of isomers or homologues. Pigment mixtures can also be usedinstead of a pure pigment. Depending on its solubility in the liquidused for dispersing the pigment, the 1- or 2-phenylthio-anthraquinonedye may dissolve partially or completely therein upon dispersion.

Some compounds of formula (I) or (II) are particularly preferred andnovel.

Thus, the invention also relates to a compound of formula (I), whereinat least one of R₁, R₂ and R₃ is SOR₁₀, SO₂R₁₀, SO₃R₁₀, SO₂NR₁₁R₁₂, CN,COR₁₀, COOR₁₀ or CONR₁₁R₁₂, or at least one of R₆, R₇, R₈ and R₉ isSO₂NR₁₁R₁₂, with the proviso that the compound is not of formula

or a compound of formula (II), wherein at least one of R₁, R₂ and R₃ isSOR₁₀, SO₂R₁₀, SO₃R₁₀, SO₂NR₁₁R₁₂, CN, COR₁₀, COOR₁₀ or CONR₁₁R₁₂, or atleast one of R₆, R₇, R₈ and R₉ is SO₂NR₁₁R₁₂, with the proviso that thecompound is not of formula

Preferred are compounds substituted by SO₂NR₁₁R₁₂, wherein R₁, R₂, R₃,R₆, R₇, R₈ and R₉ are not SO₂NH₂.

The invention also relates to a compound of formula

wherein at least one of R₁, R₂ and R₃ is SOR₁₀, SO₂R₁₀, SO₃R₁₀,SO₂NR₁₁R₁₂, CN or COR₁₀, or at least one of R₇, R₈ and R₉ is SO₂NR₁₁R₁₂,with the proviso that R₃ is not SO₂NH₂. In formulae (III) or (IV),preferably R₁, R₂, R₇, R₈ and R₉ are not SO₂NH₂.

The compounds of formulae (I), (II), (III) and (IV) can also be used forany known colouring purpose, such as for example as solvent or dispersedyes on textiles, paper or other materials, or as colourants in printinginks, plastics and coatings.

A preferred application is the use of a compound of formula (I), (II),(III) or (IV), for enhancing or modifying the colour of high molecularweight organic materials comprising pigments.

High molecular weight organic materials are of natural or syntheticorigin (e.g. polymers) and have usually a molecular weight usually inthe range from 10³ to 10⁸ g/mol. They can be in the form of fibres,surface-coating compositions (including special-effect finishes,including those for the automotive sector) and printing inks, orpreferably also in so-called resists (for example for colour filters) oras toners. Such uses will be so obvious to the person skilled in the artthat it is possible to dispense with listing them here. They are alsodisclosed in numerous patent specifications and technical works, forexample “Industrielle Organische Pigmente” (W. Herbst+K. Hunger, VCHWeinheim/N.Y., new editions continually published in German andEnglish).

The total amount of colourants, including the compounds of formulae (I),(II), (III) and (IV) as well as the pigments, is adequately from 0.01 to75% by weight, based on the total weight of colourants and highmolecular weight organic material. In the coloured high molecular weightorganic material, for example the pixels of a patterned colour filter,the compounds of formulae (I), (II), (III) or (IV) and the pigments aresuitably in a weight ratio of from 99:1 to 10:90, preferably a weightratio of from 95:5 to 30:70.

The 1-phenyl-anthraquinone dye of formula (I) or the2-phenyl-anthraquinone dye of formula (II) can be used together with aphotoresist for producing patterned colour filters, either as the onlycolourant or in combination with customary other colourants (dyes orpigments such as disclosed above), especially with halogenated copperphthalocyanine.

Accordingly, the invention also pertains to a colour filter comprising atransparent substrate and one layer or multiple layers thereon, at leastone layer being a patterned layer, the pattern of which comprises acompound of formula (I), (II), (III) or (IV) and preferably a pigment.Preferably, the pigment and the compound of formula (I), (II), (III) or(IV) are comprised together in the pattern of the same layer. However,it is also possible the compound of formula (I), (II), (III) or (IV) andthe pigment to be in two different layers exhibiting the same patternand superposed so that their coloured areas match the same pixels,preferably adjacent layers.

The number of layers in a multi-layered structure is irrelevant for thepurpose of the invention. Generally, a multi-layered structure comprisesfrom 2 to 25 layers, especially from 3 to 10 layers, on the substrate.The layers may be patterned, especially in the case of coloured, blackor electrically switchable layers, or uniform, especially in the case ofoptional intermediate and/or protective layers. The structure of colourfilters of different types, in all of which the instant invention issuitable, is well-known in the art.

Thus, the invention further pertains to a composition comprising from0.1 to 70% by weight of a colourant comprising a pigment of averageparticle size from 10 to 200 nm and a compound of formula (I), (II),(III) or (IV) in a weight ratio of from 99:1 to 10:90, preferably aweight ratio of from 95:5 to 30:70, and a liquid medium comprising abinder or a polymerisable compound.

The invention finally pertains to a process for manufacturing a colourfilter, wherein a composition comprising from 0.1 to 70% by weight of acolourant comprising a pigment of average particle size from 10 to 200nm and a compound of formula (I), (II), (III) or (IV) in a weight ratioof from 99:1 to 10:90, preferably a weight ratio of from 95:5 to 30:70,and a liquid medium comprising a binder or a polymerisable compound isapplied onto a transparent substrate optionally comprising patterned ornot patterned layers thereon, and the composition is dried and/or curedto give a patterned layer.

The drying, patterning and curing processes are well-known in the art,but are nevertheless described below in more detail for illustrationpurpose.

The invention in particular also pertains to the use of the instantpigment compositions in colour filters, which can themselves be used forexample in electro-optical systems such as TV screens, computer screens,cellular phone screens, navigation systems, electronic agendas, chargecoupled devices, cameras, color copiers, CMOS, liquid crystal displays,flexible displays, flat panel displays, plasma displays orelectroluminescent displays and the like. These may be, for example,active (twisted nematic) or passive (supertwisted nematic) ferroelectricdisplays or light-emitting diodes.

The colourants or colourant compositions of the invention will generallybe used in the manufacture of colour filters as a solution or dispersionin an organic solvent or water. There are several ways to manufacturethese colour filters, which follow two mainstreams:

-   -   Direct patterning during applying;    -   Patterning after applying the colourant.

Direct patterning can be obtained by several printing techniques, suchas impact (off-set, flexography, stamping, letterpress etc.) as well asnon-impact (ink jet techniques).

Other direct patterning techniques are based on lamination processes,electronic discharging processes like electro-deposition and somespecial colour proofing methods, like the so-called Chromalin™ process(DuPont).

For impact printing techniques, colourants may be dissolved or dispersedin water or organic solvents by standard de-agglomeration methods(Skandex, Dynomill, Dispermat and the like) in the presence of adispersant and a polymeric binder to produce an ink. Any dispersiontechnique known in the field, including the choice of solvent,dispersant and binder, can be used. The type of ink and its viscositydepend on the application technique and are well-known to the skilledartisan. Most usual binders, to which the invention is of course notlimited, are (meth)acrylates, epoxies, PVA, polyimids, Novolak systemsand the like as well as combinations of these polymers.

The ink dispersion then can be printed on all kind of standard printingmachines. Curing of the binder system is preferably achieved by aheating process. The three colours can be applied at once or indifferent printing steps with intermediate drying and/or curing steps,for example one colour at a time in three printing steps.

Inks for use in ink jet, for example piezo or bubble jet, can beprepared likewise. They generally contain a colourant dissolved ordispersed in water and/or one or a mixture of many hydrophilic organicsolvents in combination with a dispersant and a binder.

For ink jet printing, a standard ink jet printer can be used or adedicated printer can be built in order to optimize for example theprinting speed etc.

For lamination techniques, like thermal transfer and the like, a websystem has to be made: the colourant is dispersed in a solvent or waterwith dispersant and binder and coated on a foil and dried. Thecolourant/binder system can be patternwise or uniformly transferred to acolour filter substrate with the help of energy (UV, IR, heat, pressureetc.). Depending on the technique used, the colourant for example may betransferred alone (dye diffusion or sublimation transfer), or thecolourant dispersion may be entirely transferred including the binder(wax transfer).

For electrodeposition, the colourant has to be dispersed in watertogether with an ionized polymer. By means of an electrical current, theionized polymer is deionized at the anode or the cathode and, beinginsoluble then, deposited together with the pigments. This can be doneon (transparent) photo-conductors like ITO etc. which are patterned orpatternwise shielded by a photoresist.

The Chromalin™ process makes use of a photosensitive material, depositedon a colour filter substrate. The material becomes tacky upon UVexposure. The so called ‘toner’, comprising a mixture or compound ofcolourant and polymer, is distributed on the substrate and sticks on thetacky parts. This process has to be done three to four times for R, G, Band eventually black.

Patterning after applying is a method based mostly on the knownphotoresist technology, wherein the colourant is dispersed in thephotoresist composition. Other methods are indirect patterning with thehelp of a separate photoresist or lamination techniques.

The colourant may be dissolved or dispersed into photoresists by anystandard method such as described above for the printing processes. Thebinder systems may also be identical. Further suitable compositions aredescribed for example in EP0654711, WO 98/45756 or WO 98/45757.

Photoresists comprise a photoinitiator and a poly-crosslinkable monomer(negative radical polymerization), a material to crosslink the polymersitself (for example a photoacid generator or the like) or a material tochemically change the solubility of the polymer in certain developingmedia. This process, however, can also be done with heat (for exampleusing thermal arrays or a NIR beam) instead of UV, in the case of somepolymers which undergo chemical changes upon heating, resulting inchanges of solubility in the mentioned developing media. Aphotoinitiator is then not needed.

The photosensitive or heat sensible material is coated on a colourfilter substrate, dried and UV (or heat) irradiated, sometimes againbaked (photoacid generators) and developed with a developing medium(mostly a base). In this last step only the non-exposed (negativesystems) or only the exposed (positive systems) parts are washed away,giving the wanted pattern. This operation has to be repeated for all thecolours used.

Photosensitive lamination techniques are using the same principle, theonly difference being the coating technique. A photosensitive system isapplied as described above, however on a web instead of a colour filtersubstrate. The foil is placed on the colour filter substrate and thephotosensitive layer is transferred with the help of heat and/orpressure.

Indirect processes, with the above mentioned polymeric binders without aphotosensitive component, make use of an extra photoresist, coated ontop of the pigmented resist. During the patterning of the photoresist,the coloured resist is patterned as well. The photoresist has to beremoved afterwards.

More details about the manufacture of colour filters can be found intext books, reviews and other scientific articles. The skilled artisanwill associate the instant invention with the use of any such knowntechnique as well.

For example, which is of course in no way limitative, substantiallycolourless methacrylic resin are commonly used in colour filters,examples thereof which are known to the skilled artisan being copolymersof aromatic methacrylates with methacrylic acid of M_(w) from 30'000 to60'000. Such resins are highly appropriated to make films byspin-coating.

The colour filters of the invention contain the colourant compositionsof the invention judiciously in a concentration of from 1 to 75% byweight, preferably from 5 to 50% by weight, with particular preferencefrom 25 to 40% by weight, based on the overall weight of the layercomprising said colourant.

The invention therefore likewise provides a colour filter comprising atransparent substrate and a layer comprising from 1 to 75% by weight,preferably from 5 to 50% by weight, with particular preference from 25to 40% by weight, based on the overall weight of the layer comprisingsaid colourant, of a colourant composition of the invention or theindividual components of said composition dispersed in a high molecularmass organic material. The substrate is preferably essentiallycolourless (T≧95% all over the visible range from 400 to 700 nm).

The instant printing inks or photoresists for making colour filterscontain the colourant or colourant compositions of the inventionjudiciously in a concentration of from 0.01 to 40% by weight, preferablyfrom 1 to 25% by weight, with particular preference from 5 to 10% byweight, based on the overall weight of the printing ink or photoresist.

The invention therefore likewise provides a composition for makingcolour filters comprising from 0.01 to 40% by weight, preferably from 1to 25% by weight, with particular preference from 5 to 10% by weight,based on the overall weight of the composition, of a colourant orcolourant composition of the invention dispersed therein.

This colourant composition also may additionally contain othercolourants of different structure. The additional components will shiftthe mixture's spectrum hypsochromically or bathochromically depending ontheir own hue. The skilled artisan will appreciate by himself whichcolourants can additionally be used, and in which amounts, depending onthe desired colour.

In certain cases, it is advantageous to use the inventive compositionsin mixture or in combination with other additives such as wettingagents, surfactants, defoamers, antioxidants, UV absorbers, lightstabilizers, plastisizers, or general texture improving agents and soforth. Generally such additives can be used in a concentration fromabout 0.1 to 25 percent, preferably from about 0.2 to 15% and mostpreferably from about 0.5 to 8%, by weight based on the total weight of(a), (b) and (c).

Surfactants are generally used to disperse insoluble components, such asthe copper phthalocyanine pigments. They may also be used for examplewith instant anthraquinone dyes of low solubility; however, when thewhole colourant is totally dissolved, it is generally judicious not touse surfactants, as this might lead to scattering and to a lowercontrast. Cationic, anionic, amphoteric, zwitterionic or neutralnonionic surfactants are very well known to the person skilled in theart. Suitable surfactants include for example anionic surfactants suchas alkylbenzene- or alkylnaphthalene-sulfonates, alkylsulfosuccinates ornaphthalene formaldehyde sulfonates; cationic surfactants including, forexample, quaternary salts such as benzyl tributyl ammonium chloride; ornonionic or amphoteric surfactants such as polyoxyethylene surfactantsand alkyl- or amidopropyl betaines, respectively. Most preferredsurfactant, which leads to excellent colourant dispersions andespecially highly transparent colour filters, is EFKA® 3440 (CIBASpecialty Chemicals Inc.).

Suitable texture improving agents are, for example, fatty acids such asstearic acid or behenic acid, and fatty amines such as laurylamine andstearylamine. In addition, fatty alcohols or ethoxylated fatty alcohols,polyols such as aliphatic 1,2-diols or epoxidized soy bean oil, waxes,resin acids and resin acid salts may be used for this purpose.

Suitable UV stabilizers are, for example, the known benzotriazolederivatives known under the trade name TINUVIN® or CIBA® Fast H Liquidan aryl sulfonated benzotriazol, both being products of CIBA SpecialtyChemicals Inc.

The skilled artisan will obviously recognize that there are many otherpossible applications in all fields where colourants are used, such asinks, coatings and polymers. The instant colourant or colourantcompositions will prove particularly useful alone or in combination withfine or transparent pigments. Where ever the thermal colour stability isan issue, it is worth to try resolving it by using the instantcompositions, with a reasonable expectation of much better results to beobtained. Typical examples are coil- and powder coatings, extruded orinjection moulded engineering plastics as well as melt-spun fibers, thislist self-evidently not being exhaustive.

The materials used for manufacturing colour filters according toabove-mentioned and other processes are well-known in the art.

For example, a binder may be used which is alkali-soluble, preferably alinear organic polymer that is soluble in an organic solvent anddevelopable with a weak alkali aqueous solution. As such binder used ina colour filter resist composition, which is soluble in an alkalineaqueous solution and insoluble in water, for example, a homopolymer of apolymerizable compound having one or more acid groups and one or morepolymerizable unsaturated bonds in the molecule, or a copolymer of twoor more kinds thereof, and a copolymer of one or more polymerizablecompounds having one or more unsaturated bonds copolymerizable withthese compounds and containing no acid group, can be used. Suchcompounds can be obtained by copolymerizing one or more kinds of a lowmolecular compound having one or more acid groups and one or morepolymerizable unsaturated bonds in the molecule with one or morepolymerizable compounds having one or more unsaturated bondscopolymerizable with these compounds and containing no acid group.Examples of acids groups are a —COOH group, a —SO₂NHCO— group, a —SO₃Hgroup, a phenolic hydroxy group, a —SO₂NH— group, and a —CO—NH—CO—group.

Preferably, the organic polymer binder in the colour filter resistcomposition comprises an alkali soluble copolymer comprising, asaddition polymerizable monomer units, at least an unsaturated organicacid compound such as acrylic acid, methacrylic acid and the like.

The most preferred photoinitiators are the following compounds:

The photoinitiator may be used in combination with a sensitizer and/or aphotostabiliser.

The total content of the photoinitiator is preferably from 0.01 to 10%by weight, preferably from 0.05 to 8% by weight, and particularlypreferably from 1 to 5% by weight, based on the solid content of thecomposition.

Upon preparation of the dye-containing curable composition, a solvent isgenerally used. The solvent is not particularly limited as far as itsatisfies solubility to the respective components and coating propertyof the dye-containing curable composition and it is preferably selectedunder particular consideration of the solubility of the alkali-solublebinder, the coating property and the safety.

Suitable solvents include esters, e.g. ethyl acetate, butyl acetate,butyl butyrate and methyl methoxyacetate, ether esters such as1-methoxy-2-propyl-acetate (PGMEA), 2-methoxy-1-propyl-acetate,methylcellosolve acetate, diethylene glycol dimethyl ether,butylcarbitol acetate and polyethylene glycol methyl ether acrylate(PEGMEA), ethers, e.g. tetrahydrofuran, ketones, e.g. 2-butanone,cyclopentanone and cyclohexanone, and aromatic hydrocarbons such astoluene and xylene.

The instant new anthraquinone colourants and colourant compositions arewell-dispersible in solvents and/or binders and lead to excellentrheology and storage stability of the resulting compositions. Colourfilters made manufactured from these compositions exhibit outstandinghue, resolution, contrast and transparency in the spectral range above500 nm, especially from 500 to 550 nm in combination with phthalocyaninegreen pigments, together with excellent general properties such as lightand thermal stability.

EXAMPLE 1

45 g Thiophenol are added dropwise to a suspension of 100 g1-chloro-anthraquinone and 63 g potassium carbonate in 150 mlethoxyethanol at 23° C. under stirring. The reaction is stronglyexotherm and addition must be performed very slowly, and subsequentaddition of solvent improves fluidity and stirring of the reactionmixture. After heating at 120° C. for 3½ hours and subsequent cooling to23° C., the mixture is filtered on glass (porosity 3) to afford apresscake which is washed with 1 l of methanol. The presscake is in turnsuspended in 1 l water at 50° C. and again filtered on a glass filter(porosity 3). Further washing of the presscake with warm water (4 l)affords a filtrate of neutral pH. The presscake is finally dried at 60°C./5·10³ Pa for 12 hours to provide 124.1 g of powdery orange1-phenylsulfanyl-anthraquinone of formula

EXAMPLES 590-594 General Procedure

A formulation containing a colourant, an acrylic acid/acrylate polymericresin binder, an organic solvent, a photoinitiator, a polymerisablemonomer and optionally a dispersant is homogenized by stirring andfiltered over a 0.45 μm Teflon® filter. Spin coating of this formulationis performed on 52 mm×76 mm glass plates at various spinning speeds inorder to achieve various layer thicknesses. Soft bake at 80-100° C. for2 minutes affords the required thin transparent layer. UV exposurethrough a mask for 30 seconds followed by basic aqueous development andfinal post bake for 5 minutes at 200° C. results in a structuredpattern. Patterning is realised by irradiation through a mask enablingresolution ranging from 100 μm to 1 μm. The irradiation bandwidth of theUV lamp ranges from 300 nm to 410 nm with an energy intensity of 1.4mW/cm². The developing bath is an aqueous basic developer prepared fromcommercial JSR 4625™ in 2% concentration.
